It sounds more like a sql question than a postgis one but I think concatenate should helps:<br>
<span class=""><br>
<br>
UPDATE public.agriculture SET<br>

Sujet : [postgis-users] How to use UPDATE command with LIKE clause?<br>
<span class=""><br>
Hi All,<br>
<br>
I've two tables with similar columns storing text values.<br>
agriculture (name, code, geom)<br>
town (name, code, geom)<br>
<br>
I'd like to run the UPDATE geom column for a string columns.<br>
<br>
UPDATE public.agriculture SET<br>
geom = towns.geom<br>
FROM towns<br>
FOR EACH ROW<br>
WHERE agriculture."code" LIKE towns."code";<br>
<br>
The problem here is the values of 'code' columns are not always exactly<br>
the same.<br>
agriculture.code sometimes contains additional text<br>
So I've to use the LIKE command. e.g.<br>
town.code = 'MMR013025'<br>
</span>agriculture.code = 'MMR013025*701*'<br>
<span class=""><br>
in that case I also like to have the values from towns aslo.<br>
<br>
UPDATE public.agriculture SET<br>
geom = towns.geom<br>
FROM towns<br>
FOR EACH ROW<br>
</span>WHERE agriculture."code" LIKE '*MMR013025*%'<br>
<span class=""><br>
What would be the right command to do it?<br>
<br>
Thank you very much in advance.<br>
<br>

Have a nice day!<br>
